SPECIFICATION forming part of Letters Patent No. 767,475, dated August16, 1904.

Application filed March 4, 1904:.

To all whmn, it Duty concern:

Be it known that LTHOMAS F. FITZ SIMMONS, of the borough of Brooklyn,county of Kings, city of New York, State of New York, have invented anew and useful Duplex Gas-Receptacle, which is fully set forth in thefollowing specification.

My invention relates to gas-receptacles for use in heat and powergenerating stations. In these plants are generated two kinds of ases.One, producer-gas,is comparatively thin, not having as much hydrogen aswater-gas, the other kind. For commercial use the thin producer-gas hasto be enriched by certain proportions of the Watergas. Exactly whatproportion shall be used in any specific case depends upon the qualityof the respective gases and upon the particular service required; butforgiven conditions the proportions must be definitely fixed anduniformly maintained to secure the highest efliciency. In practice thishas required two separate gas-receptacles with separate inlets andoutlets, complicated meters and adjustments, and continued Watchfulnesson the part of several attendants in order to preserve the uniformity ofthe proportions passing into the service-mains.

My invention consists of a duplex tank having the features. hereinafterpointed out and claimed.

By means of my improved construction the service is facilitated in manyrespects, some of which will be pointed out.

The invention will best be understood by reference to the accompanyingdrawing, which is a perspective view illustrating one embodiment.

A represents the usual Water-tank, having four upright standards (J,secured by truss-braces D. Within this water-tank A are placed the twosemicylindrical receptacles G and H, closed at the top and sides andopen at the bottom and matched so as to fit together and Within the boreof the water-tank.

I represents brackets located on the top of the receptacles G and H andcarrying rollers that bear against the upright standards C. At each endof the straight edge upon the top Serial No. 196.55% No model.)

of each gas-tank the roller bears against the side of its adjacentstandard, whereas the roller located at the middle of the curved edge(forming with the other two rollers on its tank a triangle) bearsagainst the inner face of its adjacent standard, so that the tank isguided evenly in its vertical travel without danger of binding ortilting.

BI 31 represent pipes, shown in dotted lines and leading, respectivehfrom the interior of the receptacles G and H. The lower ends of thesepipes are brought into a parallel position and lead into a proportionalmeter, which is indicated conventionally at 0. Each of these pipes maybe divided by a longitudinal partition, so as to provide two separatepassageways, one of which is an inlet M from the generator, and theother passage-way in the same pipe is the outlet to the supplyniains,and all the passage-ways are controlled by suitable valves, stop-cocks,and the like. The proportional meter 0, by means of aproportional valve(not shown) permits a nice adjustment of the amount of gas passing fromeach of the two receptacles G and H, so as to secure a properproportional mixture of the two gases.

Two .semicylindrical receptacles, having each a capacity of ten thousandcubic feet, will suffice for a plant generating twenty million cubicfeet per day, a not unusual amount. This amount of the two gases can bepassed through the proportional meter 0 in almost absolutely exactproportions, which can be controlled at will. Owing to my presentconstruction, one single water-tank A may be employed instead of two,which economizes space and material in installing the plant and permitsthe use of a single water-supply and a single attendant. Again,the twopipes M 1V1 can be arranged in juxtaposition and lead to theproportional meter, and, furthermore, the relative heights of the tworeceptacles can be observed at a glance, so that the attendant may notethe rate at which the two tanks are discharging. Thus my constructionserves as a check upon the indications of the meter.

I do not limit myself to the precise construction and arrangements aboveset forth. For instance, instead of making the two tanks each Correctionin Letters Patnt No. 767,475.

an exact semicylinder one may be made larger than the other in variousforms, the idea being to combine the two, so as to produce a completecylinder that will operate within a single water-tank.

In practice I prefer to employ an automatic check-valve to prevent thetanks from being entirely emptied. The drawing shows a simplearrangement comprising a depending rod R, secured at the upper part ofeach tank at any convenient position and so arranged that its lower endwill enter the outlet-pipe M. A disk S is secured upon each rod at apredetermined point, so that when the predetermined amount of gas hasbeen withdrawn from the tank the disk will come in contact with theupper end of the pipe M and cut 05 the discharge. The disk S will beyieldingly mounted, as shown. By means of this automatic valve I preventthe escape of all the contents of the tank, so that the action of theengine or the exhaust cannot produce a vacuum within the tank and causethe latter to collapse.

Having thus described my invention, I claim 1. In a duplex gasometer,the combination with a cylindrical water-tank of two semicylindrical gastanks moving independently therein, substantially as described.

2. A duplex gasometer consisting of the combination of a singlewater-tank, two separate semicylindrical gas-tanks operatingindependently therein, and suitable inlet and outlet pipes from each ofthe latter connecting with a single proportional meter.

3. A duplex gasometer consisting of the combination of a single'atertank, four vertical standards rising therefrom, two semicylindricalgas-tanks operating therein, a roller carried at each end of thestraight edge at the top of each of said gas-tanks and bearing againstthe side of its adjacent standard, and a roller upon the middle of thecurved edge at the top of each tank and bearing against the inner faceof its adjacent standard.

4:. A gasometer consisting of the combination with a single water-tankof a plurality of separate gas-tanks fitting together and fitting snuglywithin said water-tank and moving independently therein.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
